CVE-2026-21138
MediumCVSS 6.9Summary
Insufficient verification of data authenticity in Smart Switch prior to version 3.7.73 allows physical attackers to install arbitrary applications.
Risk Assessment
An attacker with physical access to the device can install malicious applications, potentially leading to data and system compromise. The risk is particularly relevant for unattended devices.
Recommendation
Update Smart Switch to version 3.7.73 or later. Restrict physical access to devices and avoid leaving them unattended.
